CARL MORlTZ TRK, OF CHEMNITZ, SAXONY, GERMANY, ASSIGNORTO A PAULMATTHEEHERFURTH, OF SAME PLACE.

INVALID-BED.

SPECIFICATION forming part of Letters Patent No. 256,176, dated April11,1882.

Application filed January 10, 1882. (No model.)

.To all whom tt may concern: A Be it known that I, CARL Honrrz TRK, ofChemnitz, Saxony, German Empire, have 'invented a new and ImprovedAdjustable Mattress, of which the following is a specification. Myinvention relates to an improvement in mattresses which enables thesame, without 4further supportA from underneath, to be easily used as abedstead by hanging the mattress 1o between a head-board and afoot-board, or between either one of said boards and a wall.

My mattress is especially valuable for invalids,`as they can be movedfrom place to place upon the mattress, and have their positionproperlyadjusted thereon without disturbance and without requiring themattress to be placed vinto a bedstead having side rails.

My invention consists in combining the mattress, which is rigidly unitedto certain side zo boards, with a peculiar movable head-rest adjusted onsaid side boards, and with a peculiar foot-rest which can be raised orlowered to any desired inclination. l

Figure 1 is a side view of the mattress, show ing it to be hung betweena head-board and a foot-board, and showing the head-rest in a raisedposition. Fig. 2 is an end view ot' themattress, showing the foot-rest.Fig. 3 is a side view ofthe mattress, showing the footrest and theIhead-rest in a raised position. Fig. 4 is a plan view of the upper partof the mattress, showing the supporting-frame for raising the head-rest.Fig. 5 is a horizontal section of the lower part of the mattress on theline A B, Fig. 3.

The cushioned body of the mattress is defi. nitely secured in a frame,r, which, near the head end, has a hinged section, r', that sustains thehead-rest, and that can be raised to 4o any desired inclination, orlowered so as to be .level with the upper edge ofthe frame r.

To' the free end of the part r' are hinged the supports s s, which areconnected by a crossrod. When the part r is raised the supports i s swill drop into suitable ratchet-teeth on the 5o the position ofthesupports s upon the ratchets the occupant can change'the head-rest fromone position to another, or lower it altogether,

even when the mattress is not supported in a bedstead.

d is a wire or string, one end of which is attached to the supports s sor their brace, while the other looped end of said wire or stringextends above the part r. By means ot' this wire d the supports s s canbe pulled within the part r', as shown in Fig. 4, so that the same can6o be lowered upon the frame 0^. A triangular bag, (similar to abellows,) a, of cloth or other material, is used to cover the spacebetween the raised frame r and the frame r. To prevent this covering tfrom bulging out and get- 65 ting crowded between the frame r and thehead-.board when the head-rest is lowered, I

`attach a rubber band, g, to the frame r and said covering, as shown.This rubber band, by its tension, will draw the covering beneath 7c thehead-rest as soon as the latter is lowered.

The foot-rest k at the lower end of the mattress is movable vertically.It is in form of a pillow, k, placed upon a board, r2, to the bottom ot'which are fastened the legs Z, which are 75 properly guided by thecorners ofthe frame r. The legs l are fastened at such a point to theboard r2 that they will move close to the frame r, thereby preventingthe horizontal displace ment of the foot-rest.

To the lower part of the hoard r2 are also hinged or pivoted thesupports a: a', which, when the foot-rest is raised, will drop down andrest upon the bottom of the frame r and` hold the foot-rest in a raisedposition. (See Fig. 2.)

To prevent the board r2 being lifted too high, I fasten straps h, ofleather or otherssuitable material and of proper length, to the frame i*and board 1", all as shown in Fig. 2. 9o

e c are wires or strings which are attached to the supports wx, andpassing through a hole in the board r2 are joined by a ring, c, abovethe pillow 7c. When the ring cis pulled the supportsx w will be drawninto the position indicated by dotted lines in Fig. 2, and sliding alongthe supporting-board of the frame r eni able the foot-rest to be presseddown as far as the board r2 will permit.

To use the mattress as part of a bedsl'ead roo :it is only necessary tohang the same between head-board w and footboard 102, by means ofsuitable rings or sockets in the frame r, upon hooks n on the two endboards.

One ofthe end boards may be dispensed with by hanging one end of themattress upon hooks fastened in the Wall. y

It' it is desired to close the space which remains between the part i"and the 11ead-board fw when the head-rest is raised, a slide, g, may beusedin the hinged frame r and drawn out to support a round cushion, c.

To facilitate the lifting of the head-rest, I attach a loop, o, to theupper part ofthe same.

The mattress, when not in the head and foot rests, can still be used asan adjustable bed on the floor orother support, and as a stretcher forthe transport ofinvalids.

I do not claim adjusting the head-rest with the aid of the supportfurnished by the side rails of a bedstead, when said side rails are notpart and parcel of the portable mattress itself'.

I claim- 1. In a mattress which is definitely united to side boards, i',which are provided with ratchz 5 et-teeth, the combination of said sideboards with the hinged frame r', hinged supports s, and adjusting stringor Wire d, substantially as described.

2. The combination of the frame i', hinged 3o frame r', supports s, andstring or wire d with the bagging-cloth a and elastic strap g,substantially as described.

3. The frame i', combined with verticallymovable board r2, having legsl, and with the 35 cushion lr, straps h, braces x, and cords c, foroperation substantially as specitied.
